IMPROVEMENT IN HAY-LOADERfi The Schedule referred to Lu thqle Letters Patent and making put of the same.

To allwlwm it may concern Be it known that I, J om: Muncus BOORMAN, of Scarborough, in the countyot Westchester and State of New York, have invented certain new and useful Improvements in Hay-Raking and Loading Machines; and Ido hereby decl: re that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings forming a portion of this specification, in which- Figure 1 is a side view of an apparatus constructed according to my invention. I

:Figure 8 is a plan view, and

Figure 9, a vertical longitudinal scctionalview of the frame or rigging used upon the vehicle, and in connection with the raking and loading mechanism.

Similar letters of reference indicate corresponding parts in all the figures.

The object of 'this invention is to provide an apparatus for raking hay and other similar crops'frorn the ground, and carrying or depositing the same upon the vehicle by which it is to be transported to the stock or other place of storage or deposit, which shall operate in a more perfect manner, with greater convenience to the attendants, and with loss liability to be deranged by the vicissitudes of actual use than has hitherto been secured in machines of this class.

To enable others to understand the construction and operation of my invention, will proceed to describe it, with reference to the drawings. The vehicle in connection with which the apparatus is to be used may he of any ordinary or suitable kind, and is provided with a rigging, A, the construction of which will be hereinafter more fully described.

The real-most wheels of the vehicle have fastened upon their outer sides toothed or mggcd rims, A.

, Hinged upon the upper surfaces of either side of the rigging A, at. the rein-most end thereof, as shown at a, is afibar, A.

Each of these bars A extends back, and has formed at some distance hack of its hinge a" a notch or recess,

which forms a bearing for strong cylindrical studs -or pivots, a", turning freely therein, and extending inward from the adjacent triangular side frames A" of the fame-work B, which carries the elevating IllCChalh ism of the apparatus, whi h, heingthus hpng and not otherwise fastened, is'frce to settle by its own weight until brought to rest by its driving-pinion Dfalling into gear with cogged rim A, when not controlled by force applied by levers O 0'', ,through their points sliding'in and between grooved plates z at the-further end of A", so as to tilt the same, as .hereilmftrnappears. v

At the rear'endofthe'rigging is a stiff transverse. rod, 1), having at each end an arm, 11', arranged underneath the hackwardly-extending ends of the bars A in such manner that when the rod is turned bythc forward movement of the lover I) at one of its ends, the two bars A will be lifted and pushed forwarder turned upon their hinges in a curved line, as indicated in ii". 9, whereby the whole elevating mechanism is also lifted and pushed forward in a curved line, and the forward end of A", which is furnished with grooved plates slid forward upon and zdong-levers U 0'', so

that pinion l) is revolved around and raised upon cogged rim A in corresponding curve, without being ungeared therefrom, and the elevation oftlre wholeis. somewhat increased, and may he thus adjusted to suit I difi'erences in ground travers d or in the crop operated upon.

um-m A which is necessaril vcr much exa 'erated in the drawings to allow a clear exhibition of it,

were made shorter, so as to'lcssen the space between hinge afand arm I), the curve described by stud a" would he sharper, and its forward movement relatively increased, so that a perfect adjustment of the gearing would he obtained for allpositions, as above descrihcrh That the arms 1: of the rod 1) maybe retained in position to hold the aforesaid bars in their elevated condition, tho lever-b? is furnished with a spring pawl, which works into a fixed ratchet placed in snitahlorolation thereto and to thelevc'r itself.

Passing transversely across the rigging A, SUll'lClVllillh in rear of the center thereof, is a rod, 0, upon t'heends of which are two forwardly-oxtondiug lever-arms;

marked respectively 0 and c", the flame-r being also extended hack to form a kind of lever, and having pivoted to it a supplemental lcvor, c, thoinner'ond of which is arrzmgcd in snclrrelation with alarm-allymoving spring pawl, c, pivot-ed to the lever or leverarm a, that when c and the rear portion of c are not brought together, the pawl will hold within and against one of the notched shoulders ofa ratchet-plated", at-

tached to the ad jacentside of the rigging, in such a way that the forward ends ofthe lever-arms c and e.

will serve as stops to resist any further npwaidmove ment of .the forward 'fiXi-TPmit-iPS of the side frames,

and, by means of grooved plates 2, will also resist any downward movement, and hold said arms A fixed in whatever position they may thus be placed, thereby serving to hold the pinion I) looked in or out of gear with A, as may be desired.

By the supplemental lever 0 it is caused to automatically detach the pawl from the ratchet-plate d", and then acting upon the rearwardly-projecting portion of the lever or lever-arm 0, will raise the same, and by turning the rod 0, turns downward both leverarms 0' c", and thereby depresses the forward ends of the side frames A, the object of this being to bring the dri ing pinions of the elevating mechanism out of gear with the eogged rims A of the rear wheels of the vehicles, as hereinafter more fully explained.

The several parts are kept in this position, when desired, by the catching of the pawl 0" upon an upper shoulder of the ratchet-plate d,

In order to return the parts to their former position, with the driving pinions in gear with the cogged rims A, it is only necessary to detach the pawl from the ratchet-plate by bringing thesupplemental lever c nearer the rear part of the lever-arm 0, while depressing the same.

The 'two side frames A" are connected at their rear ends by a nearly vertical frame, B, forming, in connection therewith, the frame-work of the elevating portion of the machine.

This frame 13 has at bottom a transverse driving-shaft, d, which is driven by pinions D on either end, and which are themselves driven by rims A on the rear wheels of the vehicle, and are furnished with pawls and ratchets, so that a reversal of their movement will eause no detriment to the machinery actuated by them.

Upon such shaft d is a series of pulleys, f, carrying endless belts C, which extend upward over pulleys g at the top of the frame 13.

The frames which carry these pulleys g are capable of being adjusted to regulate the tension of the belts by ratchet-screws u, fitted with spring pawls t.

Each belt is furnished with a suitable number of forks, each having two or more tines. as may be preferred.

These forks are so shaped as to have shoulders o, the purpose of which will presently herein appear, and are pivoted or made capable of turning in suitable bearings, by which they are attached to the belts.

The driving-shaft d has fixed upon it, intermediate with its pulley f, grooved pulleys f.

Arranged in line with these, near the upper part of the frame B, and upon pivots provided in adjustable bearing -i are the grooved pulleys g. From the pulieys f, to and over the pulleys g, run endless metal or com position bafids m.

These endless bands in are, when using two-pronged forks, as in the drawings, situated one upon either side of each endless belt 0, and are so placed that, as the forks are carried upward at the front of the frame B by the movement of their endless belts, their shoulders 0' will strike and rest against the endless bands m in such a way that the forks are held in'the posit-ion required for holding the hay upon them but, on reach ing the tops or upper end of such bands and passing beyond the same, will he suffered to drop, to disengage the hay therefrom, as necessary, in its way toward deposition upon the vehicle.

Attached in any suitable manner, atthe back of the clearing'bars, as shown in fi l, is a transverse bar, as, so arranged that when the tines of the carrying forks are dropped to release or discharge the hay,

they will pass immediately underneath such bar and have their clearance very materially facilitated thereby.

Fixed guides may, ifdesirechbe substituted in place of endless hands m, but these latter are very much pret'erred.

Attached to the upper part of the frame B, but ca pa-hle of detachment therefrom, is a framework, E, which carries a fiu'wardly-curving deflecting surface, E, of elastic wood or sheet-metal. Extending downward from this, betwe en the endless belts, are a number of clearing-bars, E", and alternating with these are supplemental clearing-bars F, the lower ends of which faces of the belts. As the belts rotate, the tines of the forks pass upon either side of the lower ends of the supplemental clearing-bars 1 which, from their elastic nature, notonly prevent the hay being dragged behind them and between bars E, but facilitate its passage upward by receiving and imparting back whatever momentum may be lost by the gradual clearing to the upper surface E the tremor received from action of the belts, to overcome the tendency to clog, which would exist in a more rigid frame.

Hung upon or attached to the front of the frame E, parallel or nearly so with its inclined or curved surface, is a curved chute, G, the sides of which are closed, and which is attached to the frame E by book portions the top, the others upon lateral projections m at the sides of the frame E, as shown in fig. 1.

This chute, it; will be seen, is so arranged that as the hay is carried upward by the forks it will traverse the chute, and be ejected from its upper end forward upon the vehicle in front.

The rake by which the hay is gathered from the ground and presented to the elevating mechanism is carried by a separate supporting-liarne, G, attached by suitable appliances to the rear of the vehicle.

-The' rake itself is more fully represented in fig. 6.

The rake-head r is provided at intervals with transverse supporting pieces 4, upon which are placed the rake-teeth 8, each formed with an oblong loop, s, at a suitable distance above its point or shoe m within which its supporting pieces 1' are placed.

The rake-head is further furnished with a short arm, s", projecting forward in front of eachsupporting piece, and occupying part of the forward portion of the loop s in each tooth 5.

Upon this arm. is a spiral spring, 1, which presses the rake-tooth forward, yet allows it 'to yield upward and backward when its point strikes an unusual obstruction, while its point is guided upward by the elbow-shape form of loop s, to facilitate its clearance therefrom.

The retention of each rake-tooth in place is profor by this spring, and also by the grooving of the upper and under sides of the supporting-piece upon which it is fitted.

The forward end of each tooth is furnished with a peculiarly-shapedshoe, m. y

This shoe is nearly fiat upon its upper surface, to which .the tine is attached, slantingforward and downits under side made curved in its longitudinal section, in such manner that, as the machine is drawn forward with the shoes of the rake-teeth running upon the ground, the points of the shoes willbe at a'slight distance, say one-half an inch from the surface, so thatthe teeth may pass over slight obstructions, and thereby obviate danger of sticking in the ground and interfering with the elfieient action of the appa- .ratus, the widening of the loop 3 opposite back extension 1'', allowing a slight play for this purpose, with out pressing back springs T", which only yield to more considerable obstructions,- as above stated. The rake-head is provided at one end with a backwardly-extending arm, a.

To this is attached a vertical rod, it", provided with a stud or book at its upper end, by which it may be hooked against the adiaceut portion of the rigging to are provided with shoes resting upon the forward sur-' of the forks, aswell as imparting and propagnting'up m'm", catching and suitably fastened, the one upon ward, with its point turned slightly upward, and with.

bands 0, and the remaining portion alternating with them reach higher, so as 'to nearly ,touch the hereaftor-described sleeve 0 of the driving-shaft d,- when the "samelis in' action, thus preventing th hayfrom slippling beyond, all arranged in such position that the three of the elevating-tbrks may pass between them in the operation of the machine; This construction of the rake-teeth preventing the hay from slippling through, and enabling the hay to be taken therefrom by the forks with very great facility.

In using the apparatus attached in rear of the ve; lricle', ashereinhefbre explained, the forward movenrent of the whole causes the rake-teeth to gather the hay from the ground. The hay passing back upon the rear portions 8'' of the teeth is llftedtherefrom and carried upward by the, forks on the endless belts, and info andth'rough the chutes, the forks being meanwhile kept in position to sustain and carry the my, by the contact of its shoulders 0' with -the endless guides or hands m. These bands meanwhile 1mpart their momentum to the ascending hay man thgir straight portions shall have passed behing the clearing-bars E and F, as shown in fig. 5, at a point opposite the upper portions of said bands in; here, by contact with cross-bar z, suitably placed, they are at once disengageo'from the hay, and made toslide helrind said bar :0, imparting, at the same time, their remalning momentum to the hay. I

The hay, thus left in the upper part of the chute,

is continuously pushed upward by the pressure ofv that carried up below it by the action of the forks,

and being prevented from clogging by the elastic character of frames E and G, is finally ejected forward upon the rigging carried by-the-w'ehicle.

It will be' noticed that when, for any reason, it is .desired to elevate the rake-teetlr from the ground, it

may he'done by manipulating the rod u.

When it -is necessary to lift the elevating mechan ism without throwing it out of gear with the cogged rlms A, thelever b is actuated to raise the parts A,

in which the side-frames A" are pivoted, as lrereinbefore fully explained, and when it is sought to throw. theelevaling mechanism out of gear, it is. done by operating the lever c to depress the forward parts of the side frames A, to bring the driving-pinionseut of gear with the-cogged rims;

1n order-to prevent the hay from clogging the driving-pinions, the cogged rims, &c., there is attached to each end of the shaft (Z, a shield, I, shown indietail, and on an enlarged scale in fig. 7.- I

The plate or flat portion extends forward upon the inner sides of the rear wheels of the vehicle, and also back far enough to guard the adjacentdrivingpinion. A

It is constructed with a clasp, the two parts, j k, of which are hinged together at top, and are furnished with a recess or socket. jt, for gripping one of the cross-bars of the frame B, and with a sleeve-like por tion, 0, for clasping upon the shaft d.

The two parts j k, are brought toward each other to be clam ed in place, as just indicated, by means of a screw, at the lower ends thereof.

, In order to prevent the hay from winding upon the shaft ll, this shaft has provided upon it, intermediate with its several pulleys, a series of fixed sleeves,

a, which are necessarily made in two sections, bolted together and kept fromdurning-upon the shaftby suitable connection with the adjacent uprights of the frame B, supporting the parts under consideration.

In order tofacilitate the attachment of the shaft 11 to the frame B, the hearings ofsuch shaft, whethe made in one or two sections, .are held in'plaee upon the lowereuds of the uprights just referred to, lay-suitable metal st raps fastened to the upright by transvers bolts. 1

When desired, the chu'te, clearing-bars, &c., ma

be detached, and above each of the guides at is placed a cap-piece, wflyhich forms a continuation of th frame, so that,'as the apparatus is drawn along, t forks, instead of dropping the hay in front, will b so kept-in posit-ionas'jto carry it back over the to of-tlre apparatus this latter being thus enabled abt as a lray-tedtfer when required. I

'WhatI claim as my invention, and desire to secure by Letters Patent, is- 1 l. The transverse rod 0, furnished with lever-arms c c in combination with; the supplemental lever c, pawl c, ratchet-plate di, and the frarne-work, carrying the elevating mechanism, whereby such framework may be tilted tothrow the elevating mechanism out of gear with the cogged rims A, substantially I asand for the purpose herein-set forth.

2'. The bars or parts A, pivoted or hinged to the rigging provided with bearings for the studs or axles of the fi'anlrg g'zork, carrying'the elevating mechanism, and haying combined therewith the operatinglever b, and'transverse red I) with thearms b, whereby theelevating mechanism,'when desired, may be lifted and adjust-ed at any desired height from the ground without throwing the driving-pinions-out ofgear with the rims A, substantially as herein set forth.
